APPLICATION FILED ocr. i4, 1916.

YU. L HINSLL- @Mcm my ll,222,34l'7.

To aU rwhom t may concer/a.'

Be it known that l, Davo) L. AINSLRY, a citizen ot' the United States, residing at Mammoth, in the county of lllestmoreland aud State of Pennsylvania, have invented certain new and useful Improvements in Brakes, of which the following is a specili- 'cation, reference being,T had to the aecominvention to provide a novel and improvedI Ybrake operatmg in an automatic manner tor preventing the backward travel of a car in the event a coupling' between two of the cars or at Yany point in the train of cars should be broken.

Furthermore it is an object of the invention to provide a novel and improved brake of this general character including a dog" constituting a part of a coupling which, in the event of the coacting ears becomingr separated or the train breaking' at any point, will rock by gravity and coact with the trarkway to prevent backward movement ot the car or cars.

The invention consists in the details of construction and in the combination and arrangement of the several parts ot my improved bralre whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and ad 'antageous for use, ali as will. he hereinafter more fully set forth.

The novel features ot the invention will hereinafter be definitely claimed.

ln order that my invention may be the netter understood, I will now proceed to describe the same withreferenee to the accompanying drawings, wherein- Figure 1 is an elevational view illustrating' a brake constructed in accordance with an embodiment of my invention; and

Fig. 2 is a view in perspective of the dog included in my improved brake, certain ot the parts coaetingr therewith being; indicated by dotted lines.

As disclosed in the accompanying draw-` ings, C+C denote adjacent cars of a trainv Specification of Letters Patent.

and preferably coi'nprisinp; the rear or tail end of a train. i

B denotes a brz he dop; substantially in the term of an l.n with the foot portion l thereof substantially vertically disposed. "-.vhen said dog;1 is in normal position. with the stein portion 2 thereof directed on a predeterminati longitudinal eu'val'ure and which contacts with the under surface of the kiedy oft the rear ear as is believed to be clearly disclosed in the accompany j drawings. y

The portion l ot the dog' B is provided with the longitudinally spaced openings l through which are disposed the linlts l and extending' .in opposite directions. i forwardly disposed link is adapted to be con neeted to the coupling il ot the forward car through the medium et the draw pin. e, while the rear "ardly disposed linll; 5 is engaged with the clevis 7 coupled to the dravv bar D et the rear car through the medium et the pin 8, lit will be understood that it the requirements et practice so necessitate the links 4 and 5 may be each connected with a coupling; il carried by both of the ca C or it preferred each of said links may have coaeting' therewith a clevis engaged di rcctly with a draw bar.

ln practice it will be evident that should the cars C-C be separated or the train broken at any point in ad ance ot said cars, the brake dopx- B will overloalance and drop drm'nwardlj.' to the position indicated by dotted liuesin Vinyl and coact with the track bed to hold the rear car' lll or the separated portion oil the train against backward travel and which `is of especial import when y the train, is being' drawn up an incline as generally employed in mines or on inclines4 ot any description.

From the foregoing description, it is thought to be obvious that a brake constructed in accordance with my invention is ot an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason ot the convenienee and facility with whici it may loe assembled, and it will also be obvious that my invention is susceptible ot some change and modification without material departure from the principles and spirit thereof and for this reason l do not wish to he understood as limit-ing myseliE to the precise arrangement and formation of the several,

parts herein shown in carrying out my inn vention in practice.

I claim:

1. In combination with adjacent cars, a brake dog interposed betwcensaid cars and substantially in the form of an L with the footportion-thereof upwardly directed, and means pivotdly engaged with the foot of the dog at longitudinally spaced points adapted to be coupled to the adjacent cars.

2. In combination with adjacent cars, a brake dog interposed between said cars and substantially in the form of an L with the foot portion thereof upwardly directed, and means pivotally engaged with the foot of the dog at longitudinally spaced points adapted to be coupled to the adjacent cars, the stem of the brake dog being,r rearwardly disposed and adapted to contact with the lower structure ot' the rear car when the same is in normal position.

3. In colnliination with adjacentcars. a brake dog Substantially L-Sllaped in form, the foot thereof being upwardly directed and the Stein rearwardl)Y disposed length to extend beneath the body of the rear car, links pvotally engaged with the foot of the dog at longitudinally spaced points. Said links being oppositely directed and adapted to be coupled to the ear.

In testimony whereof I hereunto aiix my signature in the'presence of two Witnesses` D. L. AINSLEY.
